What Is Dark Tea?

2021-10-08 14:00:04

Dark tea is one of the six major teas in China. It is a fermented tea in the true sense in which microorganisms participate in the formation of quality during processing. Black tea is the world's tea with the largest production and sales, except for black tea and green tea, and it is also one of the most distinctive teas in China. The early steamed Qingtuan cake green tea became the original prototype of black tea due to long-term baking and drying and long-term incompletely sealed transportation and storage.

During the Northern Song Dynasty (1074), Sichuan used green hair tea to make it black and autoclaved to make "black tea" for border trade. Due to historical reasons, the black tea producing areas in China are currently mainly concentrated in Hunan, Yunnan, Hubei, Sichuan, Guangxi and other places. Due to the different characteristics of raw materials in various regions, or due to differences in processing habits accumulated over a long period of time, they have formed their own unique product forms and products. Quality characteristics. At present, the main varieties of colors reserved include Pu'er tea, Fuzhuan, Heizhuan, Huazhuan, Qianliangcha and so on. The product forms include compacted brick type, compacted basket type, compacted tuo cake type and compacted column type. Most of the black tea processing and packaging methods follow the history, and the packaging uses natural materials such as baskets and paper. Therefore, dark tea is one of the six major teas in China that has the best heritage and preserved history.

Dark tea belongs to post-fermented tea in which microorganisms participate in the transformation of substances. In recent years, a series of scientific studies have proved that in the process of processing, storage and transportation of dark tea, due to the action of extracellular enzymes of microorganisms, many biochemical substances that are not available in other teas or have a low content are produced, which is different from other teas. The omics features of functional substances of this kind have unique health care effects in regulating glucose and lipid metabolism and protein metabolism.
